Classics of literature to the tune of popular songs
It has been pointed out that the opening line of Milton's Paradise Lost goes remarkably well to the tune of the Flintstones: "Man's First / Disobediance / And the fruit of that forbidden tree". Pondering this, I noticed that the first line of Macbeth goes remarkably well to the tune "Happy Days are here again":
"Happy days are here again
The skies above are clear again"
"When shall we three meet again
In thunder, lightning, or in rain?"
The next few lines sort of fit, although it works better if you change them a bit. Do you know any other great works of literature that can be sung to a jaunty melody? Keep it to yourself then.
